Welcome from Arizona.
Welcome Aboard! I am not a JK owner but 3.5 to 4 inches of lift seems like a lot to fit 33s. I may be wrong and maybe someone else can give you more detailed information. If you want to do that much lift you always can but I don't think you would NEED that much to clear 33s. The higher you go the more involved and complicated lifts can get. If you are not getting the answers you are hoping for you could try reposting this in the JK section where you will probably get a greater response. The Wisconsin section of this forum is not super active. I know, I am from Wisconsin so I check this section semi-regularly. The other thing you can do is search the forum as well as scroll the JK section and look for similar questions, there are always a lot of lift/tire questions.Have a 2013 Sahara JK Unlimited still with the stock wheels; tire size is currently 255/70R18. Love it to death, but it needs bigger tires for a more "Jeep-like" aesthetic look.
Saw a nice setup the other day with a wheel size of 325/60R18, so that is what I'm shooting for.
325/60/18 33.2"x 13.3
Full disclosure: I am not sure of the offset / backspacing of these stock rims, so if anyone knows, it would save me some time and effort removing the spare (and knowing me, mismeasurement). If it helps, here is a photo of the wheels.
Based on advice from a supplier, they suggested 10" wheels for that size tire, and a 3.5 to 4" lift to provide enough clearance. They also mentioned that much lift might require a brake line extension, as well as a different speedometer gear for the bigger tire.
There are different types of lifts, and hope that I can maintain the nice "smooth" ride that I currently get. Any thoughts on types/brands?
That's all I have so far. I want to avoid getting blindsided by other parts/issues, and to have everything ready for the install (and avoid having to overpay for unforeseen parts at the dealership), so if anyone has any additional insight it would be appreciated.
I don't know about the technical part of rgreen65's advice (I have an old YJ) but the first paragraph is spot on. Hang out here on the forum for a while, watch for posts of successful modifications and formulate a plan based on how you want to use your Wrangler. Once you have a clear plan, post it in a new thread and ask for comments. You'll find the more experienced Jeepers to be very willing to help.rgreen65 gave great advice!!!
